They do that every time there is a shooting. However, not a word when knives were used in killings. They should be screaming about illegal aliens who kill huge number of Americans.
No they don’t. They don’t shriek about gang shootings (mass shootings, mass murderers) or Illegal Immigrants that kill Americans. Like Obamacare REAL goal was “single payer”, the shriek from the Left is to kill the Second Amendment. (and the First, heck, the entire Constitution)
